Reverse orientation of eliptically polarised light refers to the phenomenon in which the direction of the electric field vector of the light wave changes from clockwise to counterclockwise (or vice versa) as the light travels through a medium.
In regular polarisation, the direction of the electric field vector remains constant as the light travels through a medium. In reverse orientation, the direction of the electric field vector changes, resulting in a reversal of the circular or elliptical polarisation of the light.
Reverse orientation of eliptically polarised light is caused by the presence of certain types of materials, such as crystals, that have different refractive indices for left and right circularly polarised light. This results in a change in the direction of the electric field vector as the light passes through the material.
Reverse orientation of eliptically polarised light is used in various scientific fields, such as optics, materials science, and spectroscopy, to study the properties and behaviour of different materials. It can also be used to manipulate the polarisation of light for specific applications, such as in optical devices and sensors.
Yes, reverse orientation of eliptically polarised light can be observed in everyday life, though it may not be noticeable to the naked eye. It can be seen in certain types of crystals, as well as in certain types of light sources, such as lasers, which produce circularly polarised light. It is also used in some types of 3D glasses and polarising sunglasses.
